REGIS PAPER COMPANY, OF NEXV YORK, N. Y., A CURPORATION OF NEW YORKAPPARATUS FOR FILLING VALVE BAGS Application filed December 26', 1928.Serial No. 328,449.

This invention relates to apparatus for v filling receptacles, andespecially valve bags.

More particularly, it has to do with improved means for dischargingmaterial from afixed receptacle to and through a filling spout mountedon a weighing device, with connections whereby the discharge is stoppedby the action of the weighing device.

Specific features of the invention will ap- Ii.) pear as the descriptionproceeds.

The apparatus illustrated on the drawings comprises side members uponwhich the working parts are supported. Above thesemembers there ismounted a hopper 21, above which they may be a continuation of a storagereservoir 22, or any suitable means for guiding or feeding material intohopper 21.

The lower end of hopper 21 expanded into a circular propeller chamber 23having a horizontal discharge outlet 24. On the side of hopper 21 andabove portion 23 there is a casing 25 in which there is feeding meansdriven by a motor 26 and adapted to receive material from hopper 21 andfeed it into the upper side of discharge passage 24.

A horizontal shaft 27 near the bottom of the frame drives a verticalshaft which is connected by a clutch to a shaft driving a centrifugalpropeller rotating on a vertical axis in portion 23 of the hopper, andadapted to discharge material through passage 24. The said clutch iscontrolled by a lever 28 connected by a link 29 to a lever 30 havinglimited oscillation on a rock shaft 31. A foot pedal 32 normally raisedby a spring 33 is connected by a link 34 with an arm 35 on shaft 31, sothat depression of the pedal acts through the rock shaft 31, lever 30,link 29 and lever 28, to close the clutch and start the operation of thecentrifugal propeller. A latch, which will be described later, keepslever 30 in clutch-closing position after it has been moved to thatposition until the latch is released. The lost motion between rock shaft31 and lever 30 allows spring 33 to raise pedal 32, when released,without affecting lever 30. i

A weighing device of the pendulum type is pivoted on knife edge 36supported on the frame. The weighing. device comprises an upper member37 and a lower member 38 connected to the upper member by brackets 39and 40. The right end of member 37, as viewed in Fig. 1, is providedwith knife edges 41 on which rest V-blocks 42 supporting a bag carrier.The carrier comprises a bottom 43,

sides 44 and back 45, the top of the sides being connected'by a bracket46 which carries a spout 47 adapted to register with discharge passage24 and to enter the valve of a bag that is to be filled. Bracket 46carries a clamp 48 adapted to secure a bag in position on spout 47. l

The lower end of the carrier is connected by a link'49 to a pivotmounted adjustably on'the frame. Link 49 is equal in length to theload-carrying arm constituted by the portion of member 37 between pivots36 and 41, and pivot 50 is adjusted vertically by means of bolt and slotconnection 51, so that the link is parallel with the arm, and isadjusted horizontally by screw 52 so as to bring spout 47 into properrelation to the discharge end of passage 24.

Lower member 38 of the weighing device comprises side pieces 53 betweenwhich there slides a weight 54 threaded on a screw 55 by means of whichit may be adjusted. The weight is adjustable parallel with the directionof the loadrarrying portion of member 37.

At the end of lever 30 opposite to link 29 there is a projecting member56 pivoted at 57 to the lever and having the upward movement of itsouter end limited by a stop 58 encountered by its inner end. A spring 59normally holds the said inner end down against the stop.

hen the apparatus is in filling position, the outer end of members 56rest-s on a wear block 60 mounted on the lower end of a trigger 61pivoted to the frame at62. A spring 63 having one end connected to theframe and the other end connected to a downwardly projecting arm 64 ontrigger 61 tends to throw the upper end of the trigger to the left untilits movement is limited by a stop screw 65 mounted on the frame; butwhen member 56 rests on wear block 60, its downward pressure overcomesspring 63 and tends to swing the upper end of the trigger to the right.

A latch 66 pivoted at 67 on member 37 of the weighing device has a notch68 which engages the upper end of trigger 61 and re strains its movementuntil the bag is properly filled. The upward movement of the left end oflatch 66 is stopped by screw 69, against which it is held normally by aspring 70. A lug 71 attached to member 37 has a surface 72 in positionto contact a roller 73 on trigger 61 when downward movement of a bagraises pivot 67 and latch 66 so as to release trigger 61 and allow it toswing under the influence of member 56.

Lugs 74 suitably mounted on the frame are provided with stop screws 75,between which there is located an extension 76 of member 37, whereby theswing of the weighing device is limited.

Mounted on the frame beneath member 37 adjacent to the stop screws thereis a spring 77. Preferably, this spring is mounted as shown in Fig. 3. Asleeve 78 is screwed into a bracket 79 on the frame, and its upper endis grooved to receive the spring snugly. Within sleeve 78 there isscrewed a hollow member 80 having a hole in its upper end, through whichthere works a screw 81 attached to a stop plate 82. By this mounting theeffective length of the spring can be ad justed as well as the upperlimit of its move ment.

Above the left end of member 37 there is mounted a switch 83 controllingthe circuit to motor 26 and opening that circuit when the switch isactuated by a plunger 84 raised by member 37 when it moves in responseto the weight of a bag.

Shaft 27 is driven constantly during the operation of the apparatus, andcarries on its end a bevel gear 85 in mesh with a gear 86 on a verticalstub shaft 87. See Fig. 10. Rigidly affixed on the upper end of-shaft 87is one member 88 of a clutch. The central portion of member 88 carries abearing ring 89 grooved for balls 90. VVit-hin the balls there runs agrooved member 91 attached to the lower end of a shaft 92.

Splined upon shaft 92 is the upper member 93 of the clutch. A spring 94rests upon a flange 95 on the upperedge of bearing member 91 and fitsaround the lower end of shaft 92 within a hollow boss 96 on member 93,and normally raises member 93 out of driving relation with member 88.

A collar 97 on a-hollow boss 98 extending upward from member 93 aroundshaft 92, has outwardly projecting pins 99 passing through forked end100 of lever 28 between link 29 and the fulcrum 101 of the lever. SeeFig. 4. Link 29 passes through a block 102 pivoted at 103 to lever 29. Anut 104 on the end of link 29 confines a spring 105 against block 102,and so exerts yielding downward pressure on the lever when the link islowered by pedal 32 and the connections previously described. A nut 106or link 29 beneath block 102 limits the upward movement of the linkthrough the block.

The upper end of shaft 92 is in driving relation with a propeller inportion 23 of the housing, the propeller comprising a disc 107 curvingupward at the middle to form a hub 108, and having around its peripherya series of propeller blades 109, which fit with but little play withinthe outer part of portion 23 of the hopper, which may be called thepropeller chamber. The blades are substantially the same height asdischarge passage 24. and are in horizontal alignment therewith.

Extending upward above propeller hub 108, there is an extension 110carrying blades 111 for agitating the material in the hopper andinsuring its downward flow into the pro peller chamber. Blades 111 maybe formed similarly to propeller blades on an airplane,

and directed so as to urge the material downward in the manner of ascrew propeller.

In the bottom of auxiliary feeder casing 25 there is a passage 112slanting downward into discharge passage 24 and of substantially thesame size. In the construction shown in Fig. 5 a screw 113 is providedin this passage, and is driven from motor 26 by means of gearing 114.Above screw 113 there are two agitator shafts 115 and 116 havingagitating arms 117. Lower agitator shaft 115 is driven in the oppositedirection from the screw by a gear 118 meshing with a gear 119 on thescrew shaft. Gear 118 meshes with gear 120 on the upper agitator shaft-116, so that the upper shaft is turned in the same direction .asthescrew If found necessary :or desirable, a shaft 121 may be providedabove hopper 21 and may be driven from any suitable source of power andaid in: feeding material to the hopper or-ke.ep ing it from cloggingtherein, agitatorarms 122 or other suitable devices being mounted on theshaft.

It. is desirable to have member '46, move vertically with the leastpraoticabie friction between it andfixed discharge spout '24. At thesame time,it is undesirable to: allow the escape of dust between thesemembers. In the construction shown in detail in Fig; 8, there issufiicient play between the metallic portions of members 46-and 24 toavoid friction between them, while a washer 123 of felt or similarmaterial surrounds the, joint and is pressed against member=46 bya:light spring 124. The felt effectually prevents the escape of dust whileyielding so readily that it interferes very little with the verticalmovement of member 46. y

. Instead of the auxiliary feeding means shown in Fig. 5, other devicesmay be used,-

sucla, for; example, as those shown in Figs. 10 and 11. s i v o In Fig.10 there is shown diagrammatically a port-ion ofa hopper 21, propellercasing 23 and propeller 107 driven by shaft 92 and adapted to dischargematerial through passage 24', these parts being similar to thosedesignated on Figs. 1 and-4 by similar numerals with the prime omitted.

Beside casing 23" there is a casing 25, in whichthere runs a propeller125 similar to propeller 107, only smaller in horizontal cross section,and adapted to: discharge material through passage 24.. Propeller 125 isdrivenby shaft 126 from motor 26, which may be controlled similarlytomotor 26.

Fig. 11 shows a construction similar to that of F ig. 10, except thatinstead of having a casing 25 for an auxiliary propeller beside ofcasing- 23", the auxiliary casing 25' is above thedischarge spout24' andis provided with an auxiliary propeller 127 rotating on a horizontalaxis. Ascrewmember 128 may :be extended from propeller 127 into hopper21 and draw material therefrom into the auxiliary hopper.

While propeller 125 or 127 is preferably of smaller diameter than. themain propeller associated therewith, it is preferable to make the axialwidth of the auxiliary propeller substantiallyequal the width of thedischarge spout, the same as with the main propeller.

Fig. 12' is a wiring diagram for motor 26. The motor'switch 129 iscontrolled by a magnet 130. Interposed in the magnet circuit there isswitch 83 and a switch- 131 operated by a member 132 connected to clamp48. When both switches 83 and 131 are closed the .flnmgnet is energizedto close switch 129.

Switch 131 is normally closed, but is opened by member 132' slidingagainst actuating roller 133 of the switch. A cam lug 134 on handie 48forces slide 132 against roller 133 and opens the switch when the handleis moved to its dotted line position in Fig. 12. When handle 48 ismovedto its full line position in that figure to clamp a bag 135 onto spout47 spring 136 retracts slide 132 and allows switch .131 to close. Handle48 is maintained against unintentional movement from the po-. sition inwhich it is placed by a spring 137, which causes sufficient frictionalcontact be tween the handle and the mounting to effect this purpose.

Switch 83 may be constructed as shown in detail in Figs. 14 and 15. Amercury switch 83 is mounted on pivots 138. The circuit of magnet 130 isthrough leads 139 and 140 connected to the mercury switch. The switch isprovided with balancing block 141 into which there is inserted the,hooked end 142 of a resilient wire 143, the other end of which isrigidly secured to the upper end of rod 84-. It will be seen that whenrod 84 is raised the switch is rocked on its pivots to the dotted lineposition shown on Fig. 12, thereby uncovering the contact attached tolead 140 and breaking the circuit through the mercury.

A hand controlled switch 144 is provided for stopping motor 26 when itis to be shut down for a considerable period,'and for use if the mercuryswitch should fail at any time to function as desired.

The operation of the apparatus will be fairly apparent from theforegoing description, but may be summarized as follows.

A suitable bag is positioned with spout 47 entering the valve, and clamp48 is moved to the position in which it clamps the bag onto the spout.This movement of clamp 48 allows switch 131 to close. Since the rightend of member 37 is in its up position at this time, switch 83 isclosed, and the closing of switch 131 completes the magnet circuit,closes switch 129 and starts motor 26. a

At substantially the same time the operator steps on treadle 32, and bythe connections previously described, closes the clutch connectingconstantly running drive shaft 27 with the shaft of the main propeller.Thus both propellers operate to force material through spout 47 into thebag.

Ordinarily the weighing device is adjusted so that it remains stationaryduring the filiing of the greater portion of the charge into the bag.When the weight in the passes a predetermined limit, the forward end ofmember 37 begins to descend and its rear end to rise, thereby swingingweight 54 upward and laterally away from fulcrum point 36. This rapidlyincreases the counterbaiancing eft'ectof the weight, so that itscontinued movement is dependent upon the continued increase of weight inthe bag, and the rate of its movement is roughly proportional to therate of increase in weight. g V

Spring 77 assists in starting the upward movement of weight 54, but asthe spring expands its lifting force decreases, so that the rate ofswing of the weight is decreased from what it would be without thespring. The parts are preferably adjusted so that the spring reaches thelimit of its expansion allowed by plate 82 at substantially the timethat latch 66 is lifted clear of trigger 61.

When the swing of weight 54 reaches the point where trigger 61 isreleased, the left end of lever 30, as viewed in Fig. 1, swings downwardand link 29 is raised. Spring 105, compressed to exert closing force inthe clutch, expands and hastens the upward movement of link 29. Normallyspring 94 raises clutch member 93 as soon as the resistance of spring105 is released. If the clutch should stick for any reason, the momentumof the parts drives nut 106 against block 102 with suflicient force tojar clutch member 93 loose, and under any circumstances this blow of nut106 insures the prompt and complete release of the clutch at the instantit is delivered. In this way the opening of the clutch and the stoppingof the main propeller is timed accurately.

After the main propeller is stopped, the auxiliary feeder continues toforce material into the bag until weight 54 is swung far enough to openswitch 83 and stop motor 26. While the varying effective force of weight5% tends to prevent its being swung farther than the position justifiedby the weight of material in the bag, the momentum of the parts issometimes such as to continue the motion of the wei hing device, afterthe main feed is stopped, to a point beyond that justilied by the weightof the material in the bag, after which it is retarded until it is lessfar than it should be, thus continuing to oscillate above and below theexact weight point. Under such circumstances, switch 83 may be opened onan excess swing, then closed on the return movement, and thus be openedand closed several times before remaining open, the open periodsbecoming successively longer.

The cessation of the lifting force of spring 7 7 at substantially thetime the main feeding device is stopped tends to dampen the swing of theweighing device; but where roller 73 is provided to run over surface 72when trigger 61 is tripped, the swing of the weighing device is stoppedpositively. This stop may be employed, or omitted, as preferred.

When the permanent opening of switch 83 indicates the completion of thefilling of the bag, clamp 48 is released and the bag removed.Thereafter, weight 54 swings back to its original position, closingswitch 83; but since the mov ment of clamp 48 resulted in the opening ofswitch 131, motor 26 is not started until another bag is put on the feedspout and clamped in position in the manner described above.

WVhile one embodiment of the invention has been described withconsiderable detail, and some alternative types of auxiliary feed havebeen indicated, it will be understood that other devices may be used forproducing two rates of feed through the feed spout, and other obviouschanges may be made Within the scope of the appended claims.
